Made this for a friend who needed some help with fire animation, figured it might be useful to someone else
this is how I approach any fire animation I do timing-wise and design wise. if I am doing something more cartoony I will use shapes that are suited to more flowing smooth transitions and a nice graphic look, if I am animating more realistically I will use more chaotic timing and a design that works better with the slight motion blur I always apply to realistic fire. real fire doent flow nice and smooth like water or smoke when viewed at real-time
I almost always animate fire on 1′s, though the cartoony fire can work on 2′s, you just have to be more careful of pops.
you can also animate more realistic fire with a slower timing, you wouldn’t want the above fire in the background of a calm scene. this is just an example using an extreme case.
Hope this helps someone who is struggling to rough animate fire that fits their specific style and scene timing.
